Oh man, Aguero would be an amazing addition, especially considering how he already has excellent chemistry with Messi. On top of that, an all South American attack? That will make opponents tremble in fear!

I think that has more to do with their respective positions and what they're ordered to do. Messi is likely instructed to stay forward, maybe even to conserve energy by not asserting too much energy in pressuring.

I wasn't trying to demean Xavi as much as I was complementing Messi by believing he's adaptable and could learn Xavi's defensive abilities.

I know the love for Aguero is strong here and I love him too but if we were to get one and only one striker, I'd much rather have a target man. I really think it will add a new dimension to our game (particularly with the new verticality). It doesn't have to be an extremely big man with bad technique. Even 5feet 10 or 11 would suffice as long as he can jump.
